Cookie Cutter Geometry

Bruce has a 3rd grade Houghton Mifflin Math Expressions geometry test tomorrow that includes the concepts: flip, turn, and slide. We did some at-home practice with this from a Constructivist perspective. Instead of worksheets, he built each type of movement with cookie cutters in a baking sheet full of flour.

This is a half turn, or half rotation.

Here’s the quarter turn.

The flip…

…and the slide. Those bunnies get around!

At the end of this I had intended to use my omnium-gatherum of cookie cutters to do a pattern activity with Jenna(2.5) in the flour. But by that point, there was flour everywhere and I was starting to go a bit crazy! I’ll have to save that idea to do with Jenna another day.
